Abstract

En fremgangsmåte for å produsere et varme- behandlet støpestål som omfatter trinnene å ta et "som støpt" støpestål som omfatter ikke mer enn 0,2 % karbon, et totalt legeringsinnhold på mindre enn ca. 4-5, en karbonekvivalent som definert i det følgende ligger i området 0,45-0,7, og avkjøle støpet etter utføring av støpeoperasjonen, utføre en varmebehandlingsoperasjon ved å oppvarme støpet til en temperatur over AC3-temperaturen for å homogenisere støpet, avkjøle støpet til en interkritisk temperatur som ligger mellom AC3- og AC i-temperaturen og tilslutt bråkjøle til romtemperatur.
